Computation Offloading Techniques in Mobile Edge Computing Environment: A Review

With the rapid increase in communication, correspondence and intuiting abilities of mobile devices, applications in such devices are getting highly diversified. Wireless mobile devices have various constraints like size, battery, and computational capabilities. As a solution to such restrictions technologies like mobile edge computing (MEC) came into existence. Computation offloading is a major attribute of mobile edge computing. Offloading of computationally exhaustive applications from mobile devices to the edge servers improves the battery life of mobile devices and enhances the functioning of applications. This paper introduces the existing computation offloading techniques. Secondly, comparing the performance of these techniques based on certain paradigms like power consumption and delay minimization. Thirdly, reviews some well-known simulator tools for the evaluation of new computation offloading approaches. Finally, highlights the issues faced and future work that is required to be accomplished to utilize the features of offloading in MEC in the best possible way.
